FASTENING DEVICE Filed ont. 6, 1928 #MJ/Q1@ V Patented Aug. 4, 1931 rarezas erica JOHN F. SCHYLANDER, OF CHICAG, ILLINOIS FASTENING `DEVICE Application filed October 6, 1928. Serial No. 310,777.

My invention relates to fastening devices and hasto do more particularly with locking devices especially adapted to be mounted on a door of an automobile or other vehicle.

An object of my invention is to provide a device of the class described which will be particularly simple in construction, inexpensive to manufacture, certain in operation, and rugged. n

Another object of my invention is to produce an article of the class referred to which maybe made largely from a small number of'relatively simple and inexpensive parts.

Various other objects and advantages oi' the construction herein shown and described will be obvious to those skilled in the art f from the disclosure herein given.

To this end my invention consists in the novel construction, arrangement and combination of parts yherein shown and described, and more particularly pointed out in the claim.

Referring nowto the drawings forming a part of this specification and illustrating a preferred embodiment of the invention:

Fig. 1 represents an elevational view, partly in section, of a device embodying my invention mounted on an automobile door, the door and cooperating body portion of the automobile being shown fragmentarily;

Fig. 2 is a sectional View taken on the line .2-2 Aof Fig. 1;

ybe made by an obvious reversal of parts.

Referring rst to Figs. 1 to 4 in the preferred embodiment disclosed, the numeral 10 indicates a door of van automobile or other vehicle cooperating with the body portion 11 of the vehicle. A plate 13 forming a part ot the locking device is secured to a cooperating casing member 14. The casing member 14 is substantially rectangular, forming, in cooperation with the plate 13, a housing having the form o a rectangular parallelopiped. This casing member 14 comprises awall 15 disposed in parallel relation to the plate 13, top and bottom walls 16 and 16' and side walls 17 and 17. rlhe top, bottom, and side walls are formed integrally with the wall 15. Outstanding iianges 18 and 18 are formed integrally with the top and bottom walls 16 and 16 and are adapted to be vdisposed against and parallel to the plate 13. The material or" the flanges 18 and 18 is punched out (as shown in Fig. 6) to form annular members 20 which are swaged to apertures 21 in the plate 13, so as to form substantially a unitary container, these apertures and annular members serving as seats for screws 21 or other suitable means for securing the device to the door 10. If desired, solder may be placed between the edges of the casing 7 and plate.

Slidably disposed within the container formed by the casing 14 and the plate 13 is a latch or striker bolt 23 having a curved beveled edge 25 as shown in Fig. 2. Except for the bevel above referred to, vthis bolt is substantially in the ferm of a rectangular parallelopiped and has a longitudinal cavity 26 formed on the tace adjacent the plate 13. This cavity houses a helical spring 28, one end of this spring being secured to a boss 30 0n the wall 17.

On the side of the bolt 23 adjacent the wall 15 of the casing member 14 isa rectangular cavity 31 adapted to house a lug 33 of a manipulating member 35. The bolt is maintained firmly in contact with the lug 33 (Fig. 1) by means of a leaf spring 34 disposed inthe cavity, this cavity being re` cessed as at 34 for firmly seating the spring. It will be noted that the lug 33 has a "curved surface at 35', the point of contact' between the lug and the wall 33 of the block, so asr to reduce friction at this point.

rIfhe manipulating member 35 is in the piece of metal or the like and comprises a Curved'h'andle portion 36 and an arm por-V tion 37 having a circular boss 39 thereon dis-k posed in a circular opening 39 of the Wall 15,A and an end portion 40 bent around as at 41 so that the end Vportion is substantially parallel to the arm portion 37. rllie end portionA 40 has a circular boss 43 formed thereon Which is substantially similar to and aligned with the boss 39 and is vseated in a-n aperture 43 of the plate 13. rlhus, thevbosses 39 and 43 serve as bearings for the rotationV of the handle 35. Aligned apertures 47 and 48 are formed in the bosses 39 and 43, these apertures being rectangular in the particular embodiment shown, for the mounting of a handle member 56 on the ot-herside of the door 10.

lnthe assembling of my device, it will be obvious that the bolt 23 is assembled in the casing member 14 With the springs 23 and 34, and the manipulating member 35 is then placed with the boss 39 seated in the aperture 39, the lug` 33 being disposed in the s1 ot 31 and bearing against the spring 34. yThe plate 13 isthen brought into place with the aperture 43 seating the boss 43 and the annular members 20 Vare then svvaged into the apertures v21.v The device is Vnow -in condition to bemounted yon a door 10 andthe handle is secured lon the opposite side thereof by suitable means.

An' L-shapedfplate 52 is secured to the edge ofthe .Wall 11 at the point Where; `the latch 23 projects, so as to reinforce and protect the Wall.

. lt Will be readily seenl that' my device is extremely simplein construction and operation. Rotation of the handle in a clockwise direction results in moving the lug 3,3 to the right, thus moving .the striker bolt 23 inthe same direction against the ,action of the Yspring 28,y and thus the bolt is moved out of in Figs. 1 and 2. The springv34 and lug 33 are so designed and positioned .that the `tension of the spring`34 remainsthe same, regardless of the position of the handle.

. Fig. 5 shows a modification of thegdevice i above illustrated invvhich a slightly diiferentform of spring is used forretaining the lug of themanipulating member in firm engagement with the bolt. In this `case.the

- striker bol-t 6Ohas1a longitudinal a-perture26 similar tothe. aperture 26 -in bolt -23 forhous-V ing acoilspring (notshown) and an aperture 63 with a curved recess-64 therein. A spring 65 vshaped ,like avcotter pinhas itscurved head 66 disposed Within the Arecess 64, this spring being adapted to function similarly to the spring 34. The aperturey 63, of course, Y being adapted to seat the lug of a handle, as

in the other embodiment.

Having thus described myrinvention, it is obvious that various immaterial modilications maybe made inthe same Without departing from Vthe spirit of my invention; hence l do not Wish to be understood as limitingmyselif'to -the'exact form, construction,

arrangement and combination of parts here- ,hav-ing .a recess .the laperture thereof,

leaf `spring theshapeof a cotter .pin having its head secured in said recess formaintaininglsaid bolt in engagementivith saidcontrolling means, Vmeans for resiliently urging said bolt out of said housing. u

ln testimony whereof, l have hereunto signed my name. i l i .JOHN rjls CHYLANDER.
